COOLING MEANS FOR NGINES.

Specification of Letters Patent.

` Patented rei). 18,1908.

Application filed February 6. 1907. Serial No. 356.108.

The invention has for its object a chea and efficient ,construction of means for coo ing the engine parts as above noted, and it embodies means for-producing swirling air currents around the cylinder and especially the headthereof, and consists in certain constructions, arrangements and combinations of lparts hereinafter. described and claimed. e or a full description of the invention and the merits thereof and'also to acquire a knowledge of the details of construction andthe means for effecting the result', reference is to be had to the following description and accompanying drawings, in which: f

Figure 1 is a side elevation of an engine provided with the improvements of *my inventicn, it being understood that ,the main parts of the engine are portrayed for the purposes of illustration only: Fig. 2V is a longitudinal sectional view of the hood which constitutes the main element of the invention; and Fi'g. 3 is a transverse section v, iew of said hood.

Corresponding and like parts are referred to in the following description and indicated in all .the views of the drawings by the same reference characters. l

Referring to the drawings, the.numeral 1 designates the bed or base of an engine, 2 the cylinder thereof and 3 the fly-wheel.

`My invention comprises ahood `4, which surrounds the cylinder 2 atone head thereof and preferably tapers toward the o end of the cylinder, as clearly indicate in the longitudinal sectional view. The hood 4 is adapted to be supplied with air, which may come from any a1r compressor or other source of supply, but preferably from a blast fan 5, tothe casing of which the reduced neck 4'* of the hood 4 is connected, so as Ato support osite to deflect t 'lhe shaft 6 of the fan or rotary blast device within the casing 5, preferably carries a pulley 7 which may-be operatively connected to the flyfwheel 3 'or any other revoluble part of the engine by means ofthe belt 8.

Located within the hood 4 the junction of the tapered main body of the hood is a transversel ex tending circular series of deflector blades 9, which are arranged aslant as shown in the drawing, so that the air which issues from the discharge .opening of the fan casing 5 and and preferably at neck 4a with the,

l said hoodin spaced relationaround the end l of the cylinder 2.

flows through the tapered neck 4 is caused i to swirl as it issues through the series of blades '9 and thence out throu h the ta ered body of the hood 4, around t e cylin er 2, or the exhaust air from the coolcr may be pipedoff, if desired. The deflector -blades 9 may be either straight or curved.`

10 designates the intake valve of the engine, which is merely shown conventionally, and 11 illustrates the'exhaust 'valve from which the exhaust gases are piped off.

As clearly shown in Fig. 2, an annular deflector 9al is interposed between the series of deector blades 9 and the blast fan, the inner edge of said deiiector 9a being spaced slightly from the c linder head and thereby servin lire air up against the cylinder hea just before it enters the set of deflector blades 9.

From the foregoing description, in connection with the dnrawing, it will .be seen that I have provided improved means whereby a continuously flowing volume of air directly around the head of the cylinder is caused to swirl around the c linder,v so as to effectively cool the same, an as the blades 9 are preferably stationary, the air, as a rotary motion is set up, is held for a short time within the hood and around the cylinder, thereby acv complishing a greater amount of work. As

the exhaust valve 11 is preferably located at the center ofthe neck 4, it will receive a small amount of air on all sides and thereby become cooled effectively. By the arrangement setv forth, the temperature is maintained by the air currents, equal at all points and dan er of uneven expansion of the cylinder Wal s andthe consequent leakage and other injurious results are avoided.

It is to be understood that changes the 'l arrangement and 'roporti'ons of the parts, within the scope o the claims, may be made within the urview of my invention.

Having t us described the invention, what is claimed as new, is:

1., ln csoling means for engines, the corn.- bination with the engine Cylinder, of a hood surrounding the, same, means for 'supporting said hood in-spaced relation to the cylinder; means lforforeing air through said hood, a series of'blades supported within the hood and arranged aslant-and adapted to cause 4tlie/ air passing therethrough to set up a swirling motion, anda deflector 9& carried by the hood and interposed between the air `forcing means and the said blades, the inner edge of said deiector 9- being spaced slightly from. the cylinder, 'as andV for the purpose set forth.

.hood in spaced relation to t 2: In cooling' inans for engines, the con bination with the engine c linder, of a hood surrounding same, means or supporting the e cylinder, means for forcing air through said hood, a series of blades supported within the hood and arranged aslant and adapted to cause the air passing therethrough to set upv a swirling motion, and a'deiector interposed between the. 'air forcing means and said` blades, the inner edge of said deiiector being spaced slightly from the e linder.

In testimony whereofv affix my signature in presence of two witnesses.
